Kyoto Inspired Egg Drop Curry Udon

Keiran Curry Udon, or Egg Curry Udon, is a traditional Kyoto dish most famously served at Tsukumo Udon near Kyoto Station. It’s known for its three-layer structure: a rich curry base, chewy udon noodles, and a thick, egg-infused curry broth poured over the top. What sets this dish apart is its use of niboshi (sardine) dashi, a flavorful stock that forms the backbone of the broth. The egg is gently whisked into the broth, creating a golden hue and silky texture that blends seamlessly with the curry. This version is inspired by Tsukumo Udon’s version, bringing that comforting, umami-packed bowl of goodness to your kitchen.

Ingredients and Substitutions

This recipe requires only a few simple ingredients, many of which you might already have in your pantry. Here’s what you’ll need:

  • Udon Noodles: Thick, chewy noodles that are a staple in Japanese cuisine, providing the base for this dish. I highly recommend using frozen udon noodles as they have the best texture for packaged udon.
  • Eggs: Whisked into the curry broth, they create a silky, smooth texture similar to egg drop soup.
  • Meat of Choice: Thinly sliced beef or pork is the most common choice for Japanese curry udon but you can use your protein of choice such as chicken thigh or shrimp. For a vegetarian option, a plant based meat alternative, mushrooms or pre-marinated tofu would work great.
  • Onion: Thinly sliced and sautéed, offering sweetness and depth to the curry broth.
  • Dashi: A flavorful Japanese stock made from dried fish (niboshi), forming the base of the soup. Use konbu or shiitake dashi for a vegetarian option.
  • Curry Cubes: Japanese curry roux, a blend of curry powder, flour, and fat that thickens the broth while infusing it with rich, mildly spiced flavors.
  • Mirin: A sweet rice wine that balances the saltiness of the broth and adds a subtle sweetness.
  • Light Soy Sauce: Provides a savory, umami-rich flavor that complements the curry and broth.meat.
  • Potato Starch Slurry (optional): A mixture of potato starch and water to thicken the curry broth if desired. Corn starch can be used as a substitute.

How to Make Egg Curry Udon

Recipe Tips

  1. Use Quality Dashi: The flavor of your broth significantly impacts the overall dish. If you have the time, consider making your own dashi from scratch using bonito flakes, niboshi and kelp. This will add a deeper umami flavor compared to store-bought versions. If you’re short on time, instant dashi granules can be a quick substitute.
  2. Control Egg Texture: For the best egg drop effect, whisk the eggs well before adding them to the broth. Pour them in a thin stream, slowly while stirring gently. This will create silky strands of egg throughout the curry rather than clumps, enhancing both texture and presentation.
  3. Adjust the Spice Level: If you like your curry a little spicier, feel free to add some shichimi togarashi (Japanese chili pepper mix) or extra curry powder to the broth.

Serving Suggestions

This egg drop curry udon is hearty on its own, but you can pair it with a light side dish such as edamame, pickled vegetables, or a simple Japanese salad to complete the meal.
